16th/17thC dyes

Today I have been refreshing my collection of naturally dyed yarn, mostly silk today, but a little wool as well. I've been working broadly from some sixteenth and seventeenth century recipes over at http://www.elizabethancostume.net/dyes

So far I've done several skeins of madder, one of madder dipped in cochineal, one of cochineal and one of weld:

Now, I'm on a black dye recipe: 

Black DyeTake 1 part 

copperas, 4 parts ground gallnuts and boil with the wool yarn or 

silk for 2 hours. Take it out and let it cool. Put it back in until it is black enough. Finally rinse clean in fresh water

Will report back in two hours as to the final colour
